Abstract

The present invention provides a kind of antibacterial resin plates, are made of the substrate layer, anticollision layer, fireprotection layer, decorative layer, antibiotic layer and the anti-pollution layer that set gradually from bottom to top.The present invention also provides a kind of preparation methods of above-mentioned antibacterial resin plate.The present invention, as partially synthetic raw material, is conducive to environmental protection and economic sustainable development using soybean oil, and anti-bacterial and anti-fouling layer of the invention has the features such as hardness is high, good toughness, impact resistance is strong.Simultaneously, the present invention uses the multilager base plate that substrate layer is made in Particular craft, anticollision layer and fireprotection layer are combined, and reaches perfect combination between each layer, also has elasticity while the intensity that ensure that resin plate, external force collision can be absorbed, while there is good anti-flammability.Multi-layer substrate surface of the present invention is coated with the coating of antibacterial and anti-pollution, and coating is not easy to be contaminated, it is easier to clean, moreover it is possible to effectively prevent being scratched.

Description

A kind of antibacterial resin plate and preparation method thereof
Technical field
The invention belongs to decorate anti-biotic material field, it is related to a kind of antibacterial environment protection plate, especially a kind of antibacterial resin plate And preparation method thereof.
Background technique
The swift and violent Great War of China's green building wall environment-friendly materials in recent years, for developing environmentally protective decorative material for internal wall society It has built consensus in meeting, with the gradually foundation of management system and standards system and environmentally friendly effect of new decorative material Enhancing, green building welcome good development.Antibacterial plate is one kind sheet in use environment as a kind of environment friendly decorative material Body plays the plate of inhibition or killing effect to bacterium, mould, alcohol mother bacterium, algae even virus etc., passes through and inhibits the numerous of microorganism It grows to keep itself clean.Antibacterial plate is mainly used for public place decoration and uses, and especially medical treatment and clean place, antibacterial plate first has to Meet exclusive requirement when basic material uses to performances such as its physics, chemistry, machinery, while to consider having this spy of antibacterial The requirement of distinguished service energy and resulting additive factor.Currently, antibacterial plate mainly chooses density fiber cement plate as substrate, Surface coating antibiotic paint is made, and this antibacterial plate surface is harder, and crashworthiness is poor, and anti-microbial property is bad, and is easy to be scraped Flower, it is difficult to repair.In addition to this, the flame retardant property of existing antibacterial plate is poor, and needs when installation through modes such as cement steel nails It can just be stably fixed on wall, it is more difficult to install.
Summary of the invention
For overcome the deficiencies in the prior art, it the present invention provides a kind of antibacterial resin plate and preparation method thereof, solves The problems such as scratch resistant performance difference of anticollision existing for existing antibacterial plate and inconvenient installation.
The technical solution adopted by the present invention to solve the technical problems is:
Present invention firstly provides a kind of antibacterial resin plates, by the substrate layer, anticollision layer, fire prevention set gradually from bottom to top Layer, decorative layer, antibiotic layer and anti-pollution layer composition.
Preferably, the anti-pollution layer is formed for anti-pollution paint, and the anti-pollution paint includes the raw material of following parts by weight: saturation 3~5 parts of three-level last of the ten Heavenly stems vinyl carboxylates, 10~20 parts of non-isocyanate polyurethane.
Preferably, the antibiotic layer is formed for antibiotic paint, and the antibiotic paint is composed of the following raw materials in parts by weight: negative Carry 2.5~3.5 parts of 0.3-0.6 parts of 7~8 parts of silicon-dioxide powdery, polyethylene wax, anti-impact modifier, the color of high valency silver ion 5~8 parts of powder, 15~20 parts of epoxidized soybean oil, 30~35 parts of ethyl acetate, 12-15 parts of titanium dioxide, 6-10 parts of sepiolite, nanometer 3-7 parts of zinc oxide, 25~45 parts of Corvic, 3~5 parts of photoinitiator, 0.02~0.05 part of UV absorbers.
Preferably, the fireprotection layer is composed of the following raw materials in parts by weight: 10~12 parts of epoxidized soybean oil, polyvinyl chloride tree It is 15~25 parts of rouge, 4~5 parts of bimaleimide resin, 1,2- bis- (5,5- dimethyl -1,3- dioxas oneself in acyl phosphorus imido grpup) 3~4 parts of ethane, 5~8 parts of titanium dioxide, 5~8 parts of nano-aluminum hydroxide, 0.12~0.2 part of dispersing agent.
Preferably, the anticollision layer includes the raw material of following parts by weight: 40-55 parts of Corvic, epoxy resin 5- 10 parts, 5~6 parts of polytetrafluoroethylene (PTFE), 2~3 parts of nano-titanium dioxide, 6~8 parts of ceramic, auxiliary agent is 0.5-1 parts.
Preferably, the substrate layer is composed of the following raw materials in parts by weight: 35~45 parts of polyvinyl chloride, haloflex 20 ~25 parts, 8~10 parts of processing aid, 10~15 parts of reinforcing agent, 10~12 parts of plasticizer, 5~8 parts of stabilizer.
The present invention also provides a kind of preparation methods of above-mentioned antibacterial resin plate, include the following steps:
(1) polyvinyl chloride is put into mixing facilities and is heated, when temperature rises to 80-95 DEG C, add stabilizer, chlorinated polyethylene Alkene is continuously heating to 120-130 DEG C, and addition processing aid, reinforcing agent and plasticizer are kneaded, by mixture after mixing 65~75 DEG C are cooled to, and machinery is mated formation on hot press, and substrate layer is made after hot pressing；
(2) Corvic, epoxy resin, polytetrafluoroethylene (PTFE) are added in extruder to stir 20 minutes at 200 DEG C, Then the mixture of uniformly mixed nano-titanium dioxide, ceramic and auxiliary agent is added, anticollision layer is hot pressed at 60 DEG C；
(3) anticollision layer is attached to above substrate layer at 60~70 DEG C, is then pressed into anticollision substrate；
